Disclosed is a packaging for a flexible secondary battery comprising a first polymer resin layer, a barrier layer formed on the first polymer resin layer to block water and gas, and a second polymer resin layer formed on the barrier layer. The thickness of the barrier layer is 30 to 999 nm. The barrier layer is multi-layered, and comprises graphene, a dispersing agent, and pyrene as a flexible linking agent, in which there is π-π conjugation (interaction) between the graphene and the pyrene. Also disclosed is a flexible secondary battery comprising the packaging.

A formed article according to one embodiment of the present disclosure includes a cylindrical base layer containing a polyimide as a main component, a sliding layer disposed on an inner circumferential surface side of the base layer and containing a polyether ether ketone as a main component, and an outermost layer disposed on an outer circumferential surface side of the base layer and containing a fluororesin as a main component.

A film composite for film packaging, having a cover film composed of a polyolefin and a barrier layer, wherein the cover film has an imprinting, at least in part, on a side that faces the barrier layer. An equalization layer is arranged between the cover film and the barrier layer, which layer borders, at least in part, on the imprinting, wherein the equalization layer is formed from a hardened material on the basis of polyurethane.

A polymer-metal sandwich structure includes a first layer made of a polymer and having a first bonding surface, a second layer made of a metal and having a second bonding surface, and a third layer sandwiched between and in contact with the first and second bonding surfaces. The first layer contains or is capable of liberating anions of a first ion type at the first bonding surface, the second layer contains or is capable of liberating cations of a second ion type at the second bonding surface, and the third layer is made of a flame retardant formed of anions of the first ion type and cations of the second ion type. A method of manufacturing the polymer-metal sandwich structure is also provided.

Provided is a window including a base layer, a hard coating layer disposed above the base layer, and a bonding layer disposed between the base layer and the hard coating layer. The bonding layer includes polysiloxane.

In devices with flexible displays, multilayer adhesive stacks may be included. A multilayer adhesive may attach a flexible display panel to the display cover layer in an electronic device. Including multiple layers of adhesive in the adhesive stack (as opposed to a single layer) provides more degrees of freedom for the tuning and optimization of the properties of the adhesive stack. The multilayer adhesive stack therefore has better performance than if only a single layer of adhesive is used. The multilayer adhesive stack may include one or more layers of soft adhesive, hard adhesive, hard elastomer, hard polymer, and/or glass to optimize the mechanical and optical performance of the multilayer adhesive stack. Soft adhesive layers may be included to optimize lateral decoupling (e.g., during folding and unfolding) of the adhesive stack. Harder layers may be included to provide rigidity and prevent denting during impact events.

A flexible display apparatus includes a first functional layer, a second functional layer above the first functional layer, a third functional layer above the second functional layer, a first adhesive layer between the first functional layer and the second functional layer, and having a first recovery rate, and a second adhesive layer between the second functional layer and the third functional layer, and having a second recovery rate that is lower than the first recovery rate.

A layered device having two base films, a conductive pattern attached to the first base film facing the second base film and a bonding layer binding the first base film and the second base film together. The bonding layer includes an opening, and the conductive pattern having an exposed portion aligned with the opening in the bonding layer. Further disclosed is a spacer attached to the first base film and the exposed portion of the conductive pattern, wherein the spacer fills at least part of the space created by the opening in the bonding layer. Also disclosed is a method of producing a layered device.

The present invention provides a composition for forming a hard coat and a laminate using the same. The composition for forming a hard coat includes at least metal oxide fine particles; a hydrolysate of an organosilicon compound; an adhesion promoting component having an alkoxysilyl group; a curing catalyst; and a solvent, wherein by introducing, as the organosilicon compound, an organosilicon compound having a hydrocarbon group having (6 to 18) carbon atoms substituted with a glycidoxy group, and an organosilicon compound having a hydrocarbon group having (1 to 5) carbon atoms substituted with a glycidoxy group, even when applied to a flexible resin substrate, the composition for forming a hard coat has excellent adhesion and scratch resistance, and bending resistance (crack resistance) and surface hardness as well.

A rollable display device having a normal display status and an expanded display status is disclosed. The rollable display device includes a display layer and an optical layer. The display layer has a greater display area when the rollable display device is in the expanded display status than in the normal display status. The optical layer is attached to the display layer through an adhesive, and the optical layer includes a base layer and a functional layer disposed between the base layer and the adhesive. The functional layer is in contact with the adhesive.
